/**
 * <p>
 * High level API for processing file uploads.
 * </p>
 * 
 * <p>
 * This class handles multiple files per single HTML widget, sent using
 * <code>multipart/mixed</code> encoding type, as specified by <a
 * href="http://www.ietf.org/rfc/rfc1867.txt">RFC 1867</a>. Use {@link
 * #parseRequest(HttpServletRequest)} to acquire a list of {@link
 * org.apache.commons.fileupload.FileItem}s associated with a given HTML widget.
 * </p>
 * 
 * <p>
 * How the data for individual parts is stored is determined by the factory used
 * to create them; a given part may be in memory, on disk, or somewhere else.
